I use the bot from 26 Oct. ETH/BTC. Initial deposit is 100$. Current total profit is 5%.
The bot works can work with Poloniex, Wex, Bitfinex and Bittrex as of now. I'm using Bittrex. There is no any limit of deposit you want to use.
Update from 2 November.
Days of experiment: 8.
Initial deposit is 100$.
Current total profit is 8%.
I guess that profitability is not a lot now because of BTC hardfork is coming and every single alt is being dumped...
